Overview
The Tettex 2830/2831 is the
result of extensive research and
years of experience testing
dielectric properties of liquid
and solid insulating materials.
It incorporates a fast and
highly advanced procedure to
measure Capacitance and tan
delta, DC resistance and
relative permittivity
Ɛr
(dielectric constant) of liquid
or solid insulating materials.

A simple
one-time-connection system
together with resistance
measurement according to
pre-selected standards
drastically reduces measuring
time. The system consists of
2830, the measuring bridge and
control unit, and 2831, the
extension unit.

The 2830
contains the controller and the
measurement part of the system
The 2831 extension unit contains
a standard capacitor, 2.5kV AC
and DC supplies and a
Temperature Control Unit.

Up to two oil
test cells (type 2903 or one
solid test cell (type 2914) can
be heated at the same time.
